COPYING-PRESS.

SPECIFICATION forming part of Letters Patent No. 260,C83, dated June 27,1882.

Application filed October 6, 1881.

To all whom it may concern:

Be it known that I, WILLIAM B WKER, residing in Somerville, in thecounty ofMiddlesex and Commonwealth of Massachusetts, have invented anew and useful Copying-Press, of which the following is a specification.

This invention relates-to copying-presses; and it consistsin theconstruction and combination of partshereinafter set forth and claimed.

Figure 1 is a longitudinal section of my invention, and Figs. 2 and 3respectively end views of the same.

A is the base, having therein a groove tapering both ways from thecenter to the holes a a. Through the base A is a regulatingscrew, D, bymeans of which the spring may be adjusted up or down in base A, andthrough the screw .D passes the screw E, by means of which the spring 0is secured to the base A.

B is the top of the press, to which are fixed bracket G and fulcrum H.

O is a spring with hinge-jointsat each end, 0 0 into which work lever 1*and bracket hinge G, respectively.

F is a lever fitting into and jointed with the hinge c of the spring 0,and, when required, fitting into the hook or catch of the bracket G.

G is a bracket fixed to the top 13, with hingejoint fitting into hinge cof the spring 0, thereby connecting the top B to spring 0 through hingec. On the top of the bracket G is a hook or catch, into which the end oflever F can be placed to hold it in position when required.

(No model.)

II is a piece of metal fixed to the top B, and which receives thedownward pressure of lever F to press the top B down.

The method of working is as follows: The lever F is unhooked from thebracket G and turned on the hinge a clear of the top B. The top B isthen turned on the hinge c and the book or other article to be pressedis placed on the base A, and the top B is then turned down on, the book,acting as a lever, which actuates the spring 0 through the hinge 0 Thelever F is turned down onto the fulcrum or block H and presses the top Bdown and aetuatcs the spring 0 through the hinge c, the other end oflever F being placed under hook or catch of bracket G, thereby keepingon the pressure as long as may be required. By the use of the devicesabove described a compound lever press is obtained which ispowerfuhlight, and durable.

What I claim, and desire to secure by Let ters Patent, is-- -Theimproved copying-press composed of the base A, the top B, theregulating-screw D, the screw E for securing the spring 0, the spring 0,the lever F, and the bracket G, in combination.
